Title: Improvements in or relating to relay systems for controlling one or more conditions or variables
IPC: G05B1/04
Filed: 1951-02-14
Abstract: 756,541. Automatic control systems. NALDER BROS. & THOMPSON, Ltd., and LIPMAN, C. L. July 9, 1952 [Feb. 14, 1951], No. 3615/51. Class 38 (4). [Also in Group XXXVII] In an automatic control system, self-holding relay circuits are energized at upper and lower limits of deviation by a detector element, and de-energized only when a predetermined correction has been made. As described, contactmaking frequency meters D1, D2 operate at upper and lower limits to control a two-way- and-off polarized contactor C1, C2. Considering the lower limit, contact M1D1 energizes contactor coil C1, which completes a holding circuit over auxiliary contact SS2 and energizes a control circuit over SS1. When the frequency is corrected contact M2D1 shorts contactor coil C1 (which is supplied through a limiting resistor R1) and the contactor drops out. Meter D2 actuates contactor coil C2 at the upper limit in a similar manner. An impulse motor type interrupter M1 may be included in the corrector circuit. Modifications: (1). Two separate contactors may be used instead of one polarized contactor; (ii) one frequency meter may define the limits of starting correction, the other meter setting the limits for stopping correction. In this arrangement, the contactor holding circuit is made over the contacts of the second meter, Figs. 2, Complete and Provisional (not shown); (iii) magnetic reinforcement of the shorting contact M2D1 may be employed, and M1D1 may be a " capacitor contact " (see Group XXXV).

Title: Improvements relating to raising and stacking bricks and the like
IPC: B66C1/16
Filed: 1935-02-05
Abstract: 447,995. Lifting stacks of bricks. MOIR, SIR A., Little Court, St. Peters, Isle of Thanet. Feb. 5,1935, No. 3720. [Class 78 (iv)] For raising stacks of bricks, a pair of bars f are pushed through tunnels in the base of the stack and through slots el in a pair of spacing-members e. Hooks h are lowered to maintain the bars in engagement with the spacing-members. A three-sided skeleton casing is then lowered over the stack, so that the lower parts of the Y-shaped members c<1> engage slideways on the members e. These members c<1> are fixed to a back wall c which hangs pivotally from arms b which are pivoted in turn to, and extend to one side of, a crane suspension yoke a. The free upper ends of the members c<1> carry a pivoted wall c<2> which is raised automatically by contact with the bricks when the apparatus is removing the end section of a big stack and falls again as the load is raised. When the casing has been lowered into engagement with the members e, sling ropes i are passed over the ends of the bars f and the whole appliance hoisted. During hoisting the load tips automatically towards the back wall c of the frame, the two sling ropes being made of unequal length to permit this. For depositing the stack, the appliance is lowered over the frame f shown in Fig. 7 ; the parts e<3> of the members e are then arrested by the surfaces j<3> and the continued lowering then causes the bars f to trip the hooks h and be spread apart by the surfaces j<3> to dump the load. By engaging the hooks h<1> with the members c<3> the hooks h may be maintained in a non-engaging position. The member e may be raised with the sling and frame for transport by passing the links k over the ends of the projecting pins l. Similarly, the member may also be transported by engaging the links m with the pins l. Fig. 8 shows the preferred attachment between the sling ropes i and the bars f. The ropes carry eyes f mounted on ball bearings on short shafts f<1> which are pushed into the ends of the tubes. A method of supporting the members j on wooden frames is described, thus enabling two or three loads to be superposed to form a single stack. Specification 288,376, [Class 78 (iv)], is referred to.
